Notes on Electrical Characteristics (all measurements use 9LRS3187B as clock source and RS=33ohms/CL=2pF test load):
1Guaranteed by design and characterization, not 100% tested in production.
2 Slew rate measured through Vswing centered around differential zero
3 Vxabs is defined as the voltage where CLK = CLK#
4 Only applies to the differential rising edge (CLK rising and CLK# falling)
9 The 9DBL411B has no PLL, so the part itself contributes very little jitter to the input clock. But this also means that the 9DBL411
cannot 'de-jitter' a noisy input clock. Values calculated per PCI SIG and per Intel Clock Jitter tool version 1.5
8 Maximum input voltage is not to exceed maximum VDD
6 This figure refers to the maximum distortion of the input wave form.
5 Defined as the total variation of all crossing voltages of CLK rising and CLK# falling. Matching applies to rising edge rate of CLK and
falling edge of CLK#. It is measured using a +/-75mV window centered on the average cross point where CLK meets CLK#.
7 Operation under these conditions is neither implied, nor guaranteed.
